The sum of all cars will be = 70 + 30 + 50 + 80 + 20 = 250
So,
<span>the probability that’s the nexts car to drive by will be red = (red cars)/(total cars)
= 50 / 250 = 0.2
</span>
the probability that’s the nexts car to drive by will be <span>blue = (</span><span>blue cars)/(total cars) = 70 / 250 = 0.28
then
</span>
<span>the probability that’s the nexts car to drive by will be red or blue
= 0.2 + 0.28 = 0.48 </span>
Answer:
P = 63.6 inches
Step-by-step explanation:
you need to find the length of the third side:
9² + 21² = c²
81 + 441 = c²
c² = 522
c = 
c ≈ 22.8
P = 18 + 2(22.8)
P = 63.6 inches
Since the number of members attending is 40, you can eliminate 17 as a possible answer, as it is smaller than 40. You can also eliminate 240 because 40 members is 60%, so the answer must be less than 80. You are now left with 67 and 73.
It is (a) because 40 divided by 67 = 0.597. 0.597 x 100 = 59.7% which is rounded to 60% of the club
